Bad

Requires a phone number to sign up to get a phone number lol

Poor staff

Got blocked my a staff member for simply using the app, wouldn’t recommend this app to anyone.

Poor communication

I was using the app as well as several of my team members, yes we use it to call people, and I then was blocked with no warning, I woke up this morning with my account blocked which my payment was charged 3 days ago funny enough… you’re not allowed to be unblocked from the app, the support people say “sorry, that’s all I can do” that’s the most robotic answer they could’ve given me.

Update Glitch

Today’s update broke it! (iPhone 17)

Poor Quality

“This is the most horrible phone service app out there. They’re so worried about their appearance? They should be more worried about function. Every survey is about appearance. My messages don’t go through to people, almost weekly. I don’t get notifications for messages, so often I’ll open the app to send something out and have messages waiting. YOU MAKE ME LOOK BAD. I am a doctor utilizing an app so I don’t have to carry two phones while raising a family and it has not only lost me business, it has failed me in showing up for my clients and operating a professional establishment. Their “support” has never helped me either but has always just pushed off the problem. I’d only recommend this app to someone looking for a CHEAP phone line to let their business FAIL.”

DEVELOPER PLEASE RESPOND

I loved this app to death. It worked great and did everything I needed it to do amazingly. Yet one day I was randomly banned and cut off from the app now when I try to log in I just get an error code and have no idea why. Please help!

Overpriced

Not worth the money

Restricted account for no reason

Save your time and money - don’t use this app!!! Restricted my account I was using for business because of zero reason and support said they can’t help. Horrible company

Has big flaws

Two biggest flaws: #1. You can’t save names of contacts in the app only. #2. When someone’s calls me, my phone doesn’t ring no matter what settings I set. I only see missed calls and have to call them back. When I do, the app uses a stranger number to make the call.

Trash

Doesn’t let me make my account so what’s the point

Error creating account

I can't even create an account. I get a 8293 error.

TOTAL FAIL FOR THIS APP!

Restricted my service without knowing why

I had sent my wife several text to see how my signature came out and was automatically blocked and their support team said they don’t know the reason why and couldn’t restore my service. Ridiculous

okay but the push notifications spam

I’m using this to manage my church calling so I don’t ignore texts or voice on my main line, but can you do something about having your daily tips and tricks as push notifications? i think they’re helpful but i don’t want the distraction of thinking i got a push notification from a real person

Spam

Even with their spam blocker I get about 20 spam calls a day. Now I’m returning calls from people who said they never called me. Junk service. The company then acts like they are surprised by spam on their public facing answer. Totally disingenuous.

Mute Messages

Good app but need to be able to mute text messages and use GIPHY

Worthless

I needed an app to provide me a second phone number for my part time job. I paid for the subscription and set up my account. Before I was even able to make a call or text there was a restricted notification. I reached out to them for help. They told me I violated the terms. I NEVER USED THE APP! So how could I violate any terms and all I did was simply set up my account. They told time to reach out to Apple for a refund. Apple denied my request. So money was stolen on an app that I could not use. Both companies completely failed to provide customer service to right their wrongs.
